Sorry for the late response on this (I'm not normally a user of
NodeCreateRule). I think your analysis of the situation is correct, so I
just applied the corresponding patch to NodeCreateRule itself and things
seem to work as one would expect -- the Node is on the stack for the
duration of the set of rules that all match the initial pattern, and then
it's popped off. Even the unit tests still continue to work, so I'm
committing the change for people to play with. It will show up in the
20030817 nightly build of Digester tonight.
Thomas, I'd appreciate it if you could try this out in your application
and report back on success or probems.
